Also Known as BBMI; MIHC; MYHL; DFNA48

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 4640

About MYO1A

Cytogenetic location: 12q13.3 Genomic coordinates (GRCh38): 12:57,028,517-57,051,198 (from NCBI)

This gene has 9 transcripts (splice variants), 122 orthologues, 43 paralogues and is associated with 1 phenotype. Biased expression in duodenum (RPKM 156.2), small intestine (RPKM 147.7) and 2 other tissues.

Summary

This gene encodes a member of the Myosin superfamily. The protein represents an unconventional myosin; it should not be confused with the conventional skeletal muscle myosin-1 (MYH1). Unconventional myosins contain the basic domains characteristic of conventional myosins and are further distinguished from class members by their tail domains. They function as actin-based molecular motors. Mutations in this gene have been associated with autosomal dominant deafness. Alternatively spliced variants have been found for this gene.
